When USB 2.0 starts comming out on motherboards, we should start to see faster CD burners. Maybe even USB hard drives. I think USB 2 has something like 400 mbits bandwidth.
Firewire (ok IEEE 1394 - Firewire is Mac) is another technology that I hope starts to kick its way into the market. Currently its main purpose is for Digital Video, but I'm sure more devices will be made for it.
